Field notes
The checker derives effective print DPI from pixels divided by print-area inches rather than trusting editable file metadata. Its platform checks also look for opaque white pixels masquerading as transparency, a problem that can produce a white box on dark apparel. The paid workflow handles up to 100 files, exports a CSV, and pads artwork to platform sizes while refusing to upscale it.
